Block copolymer and ester-terminated polyesteramide composition and uses thereof

Abstract

Compositions and methods for the preparation of a composition comprising a block copolymer and ester-terminated polyester amide solubilized in a compatible solvent are disclosed. The disclosed compositions are long-lasting, transfer resistant, flexible, and water-proof capable of complexing the active ingredient to provide such benefits. The disclosed compositions are useful for formulating cosmetics, personal care products, cosmeceuticals, and the like.

What is claimed is: 
     
       1. A cosmetic composition, comprising:
 a charge-neutral, hydrophobic block copolymer and an ester-terminated polyesteramide polymer dissolved in at least one solvent, 
 wherein the charge-neutral, hydrophobic block copolymer is styrene-isobytylene-styrene (SIBS) copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, 
 wherein the ester-terminated polyesteramide polymer is a bis-stearyl ethylenediamine/neopentylglycol/stearyl hydrogenated dimer dilinoleate copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, and 
 one or more of: film formers, emulsifiers, rheology modifiers, polymers, fillers, coloring agents, cosmetic vehicles, microspheres, or active or inactive ingredients, 
 wherein said composition is free of tackifier resin. 
 
     
     
       2. The composition of  claim 1 , wherein the solvent is isododecane, isohexadecane, isopropyl palmitate, polyglycerol diisostearate, pheynyl trimethicone, or combinations thereof. 
     
     
       3. The cosmetic composition of  claim 1 , wherein the cosmetic composition is a foundation, a pressed powder, a powder foundation, a face powder, a concealer, a blush, an eye shadow, a loose powder, a powder blush, a talc powder, a cream, a lotion, a skin care product and/or a personal care product. 
     
     
       4. A cosmetic composition, comprising:
 a styrene-isobutylene block copolymer, 
 wherein the styrene-isobutylene block copolymer is styrene-isobytylene-styrene (SIBS) copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, 
 and 
 a bis-stearyl ethylenediamine/neopentyl glycol/stearyl hydrogenated dimer dilinoleate copolymer dissolved in a solvent of isododecane, isohexadecane, isopropyl palmitate, isopropyl myristate, or combinations thereof, present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, wherein said composition is free of tackifier resin. 
 
     
     
       5. A hair composition, comprising:
 a charge-neutral, hydrophobic block copolymer wherein the charge-neutral, hydrophobic block copolymer is styrene-isobytylene-styrene (SIBS) copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, and 
 an ester-terminated polyesteramide polymer dissolved in at least one solvent, wherein the ester-terminated polyesteramide polymer is a bis-stearyl ethylenediamine/neopentylglycol/stearyl hydrogenated dimer dilinoleate copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, 
 wherein said composition is free of tackifier resin. 
 
     
     
       6. A method of preparing a cosmetic composition, comprising:
 (a) mixing and heating until homogeneous a composition comprising:
 (i) a charge neutral, hydrophobic block copolymer, wherein the charge-neutral, hydrophobic block copolymer is styrene-isobytylene-styrene (SIBS) copolymer, 
 (ii) an ETPEA polymer, wherein the ETPEA polymer is a bis-stearyl ethylenediamine/neopentylglycol/stearyl hydrogenated dimer dilinoleate copolymer present in an amount ranging from about 0.01 weight % to about 50% weight % based on the total weight of the composition, 
 (iii) a solvent or mixture thereof, and 
 (iv) one or more of: emulsifiers, rheology modifiers, or polymers, wherein said composition is free of tackifier resin; 
 
 (b) mixing and heating the homogenous mixture and one or more of: fillers, microspheres, or coloring agents until homogeneously dispersed; 
 (c) milling the homogeneously dispersed mixture until the fillers, microspheres, and coloring agents are uniformly dispersed; and 
 (d) cooling the uniformly dispersed mixture, thereby forming the cosmetic composition.
